Correct. Anything that takes a screen as an argument accepts the long names, 
but only screens 0-9 appear in clerks built-in menu, and pressing numbers at 
entsel only gets you 0-9. For other screens you have to provide your own 
menu/listbox/special screen/etc.. and you can write your own @keys to jump 
to other screens from entsel as if they were 0-9.

We use a rough standard where several non 0-9 screens have @keys that pop 
them up so they seem just like 0-9 screens but by pressing other letters or 
even punctuation.
And one of the @keys is always @keym, which does a screen "m", which 
displays a menu of all screens that can be jumped to by pressing a key at 
entsel.
So screen m ends up behaving just like a menu, but with more control over 
looks/layout/number-of-items than real menus or listboxes. But it's just a 
static screen with no input fields you can only get to from entsel or 
processing or command line flag. It's important that this not be a 0-9 
screen itself too. If it were say, screen 0, it would be possible to enter 
the screen in add-records mode, which causes a tight loop creating empty 
records as fast as the computer can do it.

The built-in screen menu, like a lot of the built-in initial dialogs, we 
don't usually allow the user to see any more so it doesn't matter much what 
it can and can't include.
